What is the function of transfer RNA?

• Carries amino acids to the ribosome and adds them to growing protein

• Copies coded message from DNA and carries message to ribosome

What is the result of a parent cell making an error in copying its DNA?

• The daughter cell will have no DNA

• The daughter cell will have the same DNA as the parent cell

• The daughter cell will have RNA instead of DNA

• The daughter cell will have DNA different from those of the other cells
